When vented from choking the nozzle, as well as in assembling the cap into the tube 10, a tube havorder that the liquid will be guided away from ing an inner diameter corresponding to the outer diameter of the portion 18 may be placed over the portion 18 and against the shoulder 21 so that the cap may be forced conveniently into the tube 10. The intermediate space 22 further makes it possible to provide room into which the portion 18 may extend when pushed, so that a comparatively large volume of fluid may be forced from the tube 14 under controlled conditions.

The flanged neck or collar 15 is secured in the end of the tube 10, between the tube and the stopper 13. The said collar has a tubular flange or spud 23. The needle 16 which fits closely in the bore of the nozzle tube 14, has a bell shaped cap 17 secured to its upper end, to serve as a convenient handle for the needle. This cap 17 fits over the spud 15 when the needle is in place as a stopper, and acts as a protective cap, keeping out dust and dirt, and protecting the nozzle tube from breakage.

In the claims afiixed to this specification no selection of any particular modification of the invention is intended to the exclusion of other modificationsthereot and the right to subsequently make claim to any modification not covered by these claims is expressly reserved.

I claim:

1. Non-refillable bottle for inks consisting of a section of a cylindrical tube made of rigid material, a stopper tightly and securely forced into one end of the tube section, a nozzle tube made of somewhat elastic material secured in the stopper, a collar arranged upon the stopper and having a spud surrounding the nozzle tube, a flange upon the edge of the tube section which secures the collar and the stopper, a needle fitting tightly into the nozzle tube and provided with a bellshaped handle which surrounds the spud, and an elastic pressure cap tightly seated in the other end of the tube section and completely enclosed by the tube.

2. A non-refillable ink bottle consisting of a rigid container portion, a closure stopper provided with a nozzle, and inserted into one end of the container portion; said stopper and nozzle being bounded by a surface inclined to the axis of the container, upon their inner ends, and an elastic pressure cap inserted into the other end of the container.
